its bearing. The collar 20 on the land side p of the machine ispreferably provided with a crank arm 29, while the other collar 20 onthe other side of the machine is provided with two arms 30 and 31. Therod 9 preferably connects the crank' arm of the rear caster wheel withthe arm 31 and the rod 32 connects the arms 29 and 30. By this means, asthe tongue or pole 26 is turned to the right or left all three of thewheels are simultaneously turned. By this means when the plow reachesthe end of the furrow it can be turned around with a very short turn.The forward end of the plow framefis preferably provided withthedepending standards 33, the lower ends of which are connected by thecross bar 34. The stand-Y ards are preferably secured at vtheir uperblyformed of a plate of angle iron. Upright non-revolving shafts 35, 35have their lower ends pivotally connected preferably by suitable boltsSti-with the plate 34 and 37 in the horizontal ortion of the cross bar10. This manner o 'mounting the shafts 35 permits their upper ends toswing either to the right or left thereby tilting said shafts intopositions inclined in either direction from the perpendicular. Fortilting the shafts I prefer to provide a horizon 40 and having itsforward end preferably engaging one of said shafts 35 the two I Thelever 38 is preferably pivoted at l2 to the cross bar .11. By means ofthis lever the shafts 35 may be tilted in either direction to a greateror less extent and may be locked moved by said lever.

l/Ve have shown in the drawings twt.l plows 45, 45, each provided with avsuitable plow beam 4-6 connected at its forward end by ahorizontal boltor pivot 47 to aelevis- `i8 having a forked forward end engaging .one.of the shafts 35. These plows and plow beams may be of any suitable orpre-- ferred construction. They are capable of swinging verticallyon thehorizontal pivots 47 and the clev'iscs 48 are capable of swinginghorizontally on the shafts 35, said or down on said shafts 35v and forthe purpose of moving them we preferably provide blocks .t9 which arearranged uponI said shafts 35 between the forks of the/clevises,

and are each provided with a projection o() to which projection a crossplate 51 is sccured. made of angle iron and to it draft links 52 aresecured to which a team may be hitched for pullin the plow. For thepurpose of raising ano lowering the plate 51 and with it the forwardends ofthe plows we provide a suitable lever o3 pivot/ed to an upright54 upon the cross plate 11, the forward end of saidlcver havingconnected to it a link 55 which is also connected at its lower end tosuitable lugs 5G secured to the plate 51. By operating the lever 53 theforward ends of the plow beams may be raised or lowered and the pointsof the plows held horizontal or tilted upward or downward.

For lifting the plows out of the Ground and holding them when raised wepre erably provide a shaft 57 mounted in bearings on. the frame ofthemachine and having-Secured to it operating lever 5S, having a latch 59adapted to engage a notched locking plate 60 secured to one of the sidebarsA 2. Mounted so astofturn freely uponthe shaft 57 are the hubs61,-each of which is The cross plate 51 yis preferablyv provided with afoot lever-62 and a projecti vfoot levers the operator can raise eitherof the plows without raising'the'other. A bail 65 is secured to theshaft -57 andpasses under both of the projecting arms 63. When theoperator'desires to raise bothv plows he does so by nieans'of the lever58 and he can by means' of this lever and its latch lock them in anelevatedA position. A suitable seat G6 is preferably provided upon theframe of the machine for the operator who, while sitting thereon, willbe in convenient position to manipulate any of the hand levers or eitherof the foot levers, and who` can also drive a team by which the plow isdrawn. l

For the' purpose of counterbalancing the weight ofthe plows andassisting in elevating the same we prefer to provide a spring 67attached to an arm 68 upon the shaft57 and connected toa stationary[part of the machine at its opposite end. We .have here shown one end ofthe spring connected b.

a' suitable eye-bolt to the seat standar lao l eral swing of the beams.

der and engage the plow beams and prevent them from swinging laterallyin either direction on the vertical shafts 35, which form pivotalsupports for the clevises to which the forward ends of the plow beamsare connected. The shaft 57 in this instance is provided with -a singlecrank arm 63 to which is connected a link 7 2 that engages the swingingrod 70. Either the foot lever 62 or the hand lever 58 may be used forturning the shaft 57 and raising or lowering the swinging rod and withit the plow beams and plows. For the purpose of holding the plows downwith a yielding pressure we prefer to provide in this instance thestirrups 73 that are connected at their lower v'end to the bottoms ofthe loop 71 at opposite s ides of the plow beams. These stirru s riseabove the plow beams and springs 14 preferably of V-shape have theirupper ends connected to the stirru 73 while their lower ends bear upon'said p ow beams. Loops 75 pass around the stirrup 73.` and above thelower ends of the spring 7ji, ho ding said stirrups and springs inposition.

Under normal conditions the plow beams are free to swing laterally butunder certain conditions said beams may be locked against lateral swingby manipulation of the swinging crank rod 70 so as to bring the loops 71of the 'crank rod in position against the p' w beams and thus lock andprevent lat- When however the crank rod is lowered its loops 71 aremoved away from the plow beams so that the latter are then free to swinlaterally under restraint of the springs. he spring system 73, 74 and 75is stron enough to serve rthe purpose assigned to t ose springs but notso much so as to prevent the lateral swing of the plow beams when thecrank 70 is moved away from the beams. l

Operation: With this plow the furrows may be cut wide or narrow, deep orshallow. The operator b means of the lever described can raise or lbwerthe forward ends of the plow beams thereby adjusting the points of theplow to' secure the depths of furrow desired. By tilting the verticalshaft 35 he can also tilt the plow beams and plows in either directionfrom the perpendicular. Tilting the plows causes them to `run to agreater or less distance into the land thereby increasing or decreasingthe width of the furrows, narily the plows are left free so that theycan swing laterally in either direction, thereby causing them toautomatically swing past stones, stumps or other obstructions.

henever desire the operator can, by means of the foot levers, raiseeither one of the plows free from the ground to pass over an obstructionor for any other purpose. By means of the hand lever 58 he can raiseboth plows and can lock them in an elevated,`

Ordiposition. By means of the levers 22 he can adjust the height of theframe from the ground and through connecting rods described the plow ismade capable of a very short turn whenever desire Vlrhen it is 7 desiredto prevent the plows from Swingin f laterally as in the plowing of aside hill, the locking means shown in Figs. 5 and 6 of the drawings maybe connected to the plow beams, thus preventing any lateral move- 7 mentof said beams.
